my car is a 2002 ta, please somebody has any idea what is wrong with the car. the car ran a 12.76 at 105.23 m/h with a 1.775 60ft. mods at that time:
air lid
3200 vig
et streets
slp loud/m cat back
transgo
stock tanny and 3.23 gears.
now it has a cam on the 230-240 duration, 90mm fast intake, 90mm t/b, kooks 1 7/8-2 to 3 1/2 collector, 3600 vig with 2.5 str, same tires time same gear, and the car ran 12.069 at 111.39 m/h with a 1.685 60ft.
im guessing is something wrong with the converter cause the seems a lot slower on the top end than what is supposed to do, i dont think this converter is very efficient at all, please any suggestion will help!!!

That vig will feel softer uptop , that would be the trade off but you have a big cam big intake big throttle body , with stock heads , that doesnt seem to be the right combo in my opiniun. I think you got some big flowing parts on your car inwhich do not need. Bigger isnt always better. I had 216/220 cam with boltons and a tci 3800 converter that would run 11.80s at 112mph in 80*temps ..

The vig3600 is a good converter. I do not think that is your problem.

Have you done any weight reduction?
What is your race weight?
Where do you race?
Your 105.23 looks a little low but it all depends on where you race and weather conditions. My ET will vary .5-.8 from winter to summer.

You trapped 6mph higher and dropped your ET by .7. Not too bad.

yes, i got the car tuned last week, my tuner said my m/p seems kinda low.

what did it put down for hp , i had my car tuned and it put down 342 at the wheels and weighed in at 3576 with me in it . I still think the parts are to big , you want to have velocity as well as volume..

the car put down 380 rwhp, but we couldnt get a torque reading cause of the converter.

I agree. Put some good high flowing heads on there and it will really fly. Some 3.73 gears will help to.

With the converter locked up his car made over 420 rwhp at 6700 rpm. The curve was still going up.

Stock heads is one problem the other problem is the large 1 7/8 headers. On my stock engine Corvette I installed 1 7/8 headers and it slowed down a ton, went down to 1 3/4 headers and ran much quicker. As the others have said I don't think you have an issue with the converter. Good Luck
